Abstract: A percolative conductive network includes bundles of carbon nanotubes and clusters of conductive particles arranged on a substrate. A plurality of the bundles include one or more points of contact with at least one adjacent bundle to form a carbon nanotube network, and the clusters of conductive particles separate the bundles in regions between the points of contact. At least a portion of the clusters form conductive pathways between adjacent bundles, and the carbon nanotube network and the conductive pathways define a percolative conductive network on the substrate.
